Friction Pad – Wool, 12" × 12" (each)

United Scientific RPWL30 is a wool friction pad that produces strong negative charges when used with plastic or rubber rods. Its coarse texture enhances charge separation.

Key Features:

• Material: premium wool
• Dimensions: 12" × 12"
• Use: best paired with acrylic or rubber rods for static charge generation
• Durability: long-lasting and reusable

Applications:

Essential for triboelectric series demonstrations, charge polarity studies, and hands-on physics labs.
